Multi-port monitoring
Capture multiple COM ports in one session for coordinated device debugging, master-slave comparison and post-incident review.
- Unified send/receive ordering
- Less window switching
- Fits gateway and master-slave test benches
Features
Features for protocol tracing, device bring-up and field diagnostics.
Scan the capabilities by real debugging jobs: connect ports, inspect bytes, validate protocols and keep field-service records aligned.

License and sync coordination
Capability Matrix
Organized around real debugging actions, not menu names.
ASCII and Hex views
Inspect text and binary protocols precisely to isolate byte-level differences, encoding issues and CRC-related faults.
- Switch between ASCII and Hex
- Built for frame-level troubleshooting
- Easier cross-checking against device docs
Network protocol support
Debug TCP and UDP next to serial traffic, covering TCP server and client plus UDP client, server and multicast, so gateway and protocol-bridge issues stay in one view.
- TCP server (multi-client) and TCP client
- UDP client, server and multicast (UDP group)
- One entry point instead of multiple tools
Timestamped logging
Attach a timestamp to each line automatically for long-running captures, incident replay and post-delivery troubleshooting.
- Configurable time formats
- Rotate logs by size or time
- Auto-wrap for reviewability
Modbus frames and checksums
Build and verify Modbus RTU frames with the built-in CRC-16/MODBUS, backed by a wider CRC-8/16/32 checksum library, all in HEX or ASCII.
- CRC-8/16/32 family: MODBUS, USB, CCITT, XMODEM and more
- Auto-append the checksum when sending
- Works with RS232/485/422
Cloud sync extension
Bring devices, licenses and message records into the backend so client-side diagnostics and platform operations stay connected.
- Device onboarding
- License status tracking
- Remote issue triage support
Built For Daily Use
Turn problem visibility into actual delivery progress.
- Customize timestamps, encoding and display modes to reduce manual translation.
- Keep frequent commands in a quick-send list and trigger timed auto-send for repeated stimulus.
- Auto-wrap and log review fit long capture sessions and production traces.
- Use Cloud Sync to connect devices, licenses and message records in one backend.
One Entry Point for Three Jobs
Use it for protocol debugging in development, interaction validation in testing and device-license coordination in operations.
Use Cases
Covers common scenarios from development to field work.
Embedded development
Use it during MCU, sensor and board bring-up to verify low-level serial links and protocol exchange quickly.
Industrial control
Fits PLC, meter and industrial device communication checks, helping isolate master-slave link and timing issues.
Gateway diagnostics
In serial-to-TCP or UDP gateway scenarios, you can validate physical-port and network-side traffic side by side.
